Error response from daemon: getsockopt: connection refused

问题

When I try to pull an image from a private Docker Registry I get the error

Error response from daemon: Get https://XX.XX.XX.XXX:5000/v1/_ping: dial tcp XX.XX.XX.XXX:5000: getsockopt: connection refused

The docker registry is definitely listening on the correct port. Running

ss --listen --tcp -n -p

Gives the result

State       Recv-Q Send-Q                                           Local Address:Port                                             Peer Address:Port

LISTEN      0      128                                                         :::5000                                                       :::*

Does anyone have any suggestions for how to solve this problem? I'm really stumped by it!

Thanks in advance!

I had the same issue, seems like it related to certificates on your registry host. Check here on how to fix that: https://github.com/docker/docker/issues/23620
